ROCKER-"CUSHION.

SPECIFICATION forming part of Letters Patent No. 608,660, dated August 9, 1898.

Application filed August 25, 1897. Serial No. 649,543. (No model.)

To all whom it may concern:

Be it known that we, JOSEPH I-I. FINK, rcsiding in Kansas City, in the county of Jackson and State of Missouri, and RAYMOND- 5 ANDLAUER, residing in Kansas City, 'in the county of \Vyandotte and State of Kansas, citizens of the United States, have invented certain new and useful Improvements in Rocker-Cushions, of which the following is [O a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in rocker-cushions.

Our invention is adapted to be used on the I 5 rockers of chairs, cradles, or similar articles. The object of our invention is to provide a resilient cushion adapted to be secured to the bottom of a chair or cradle rocker as a support or bearing therefor.

Our invention provides, further, a resilient cushion secured to and running lengthwise of the bottom of a rocker.

In its preferable form our invention comprises a resilient cylinder, as of rubber, se- 2 5 cured to the under side of the rocker lengthwise thereon. It further comprises a tube of resilient material, such as soft rubber, having its ends closed and adapted to be inflated with a fluid, such as air.

; Our invention also provides means for ad- 3' usting the tension lengthwise of the cushion after it has been placed in its seat in the bottom of the rocker. It provides, still further, certain novel features of construction here- 5 inafter fully described and claimed.

In the accompanying drawings,which illustrate our invention, Figure I represents a perspective view of a rocking-chair the rock ers of which are provided with cushions of 0 our invention. Fig. II represents a longitudinal vertical sectional view of a rocker having attached thereto a cushion of our i11- vention. Fig. III represents an end perspective view of a form of cap used to secure the .5 end of the cushion to the rocker.

Siinilarletters of reference indicate similar parts throughout the different views.

A indicates a rocker such as is found on rocking-chairs or cradles.

is placed in a groove provided lengthwise in the under side of the rocker.

O indicates'a cap, preferably of metal, secured one at each end of the cylinder-cushion A.

D indicates a cap, also preferably of metal, secured one on one end of the rocker and one upon the other end, in which are secured, re spectively, the two caps C.

E indicates a screw which extends through an opening provided therefor in the closed end of each of the caps I). The inner end of the said screw E enters a screw-threaded opening provided in the end of each of the caps O. y

F designatesthe inflating-tube, with which each cylinder B, when of the pneumatic style, is provided. This tube F is secured to the upper side of the pneumatic tube near its rear end and extends upward through an opening provided therefor in the rocker A.

It may be provided with a valve and cap similar to such as are commonly used in bicycle pneu 1n atic-tire construction for the same purpose. No novelty is claimed by us for the mechanism used for in flatin g the cushion, and any known means may be employed for this purpose.

The cylinder B may be constructed in various ways and still retain the spirit of our invention, which, broadly stated, comprises a rocker having secured to and extending substantially its full length on its under or bear ing side a resilient cushion, preferably of a cylindrical form. The preferable form of cushion and the one principally employed by us and whichhas proven very satisfactory is the form illustrated in the drawings. In this form a straight soft-rubber tube having its ends closed is employed for use as a cushion. Each end of the said tube, which, as before stated, is indicated by B, has permanently secured to'it a metallic cap 0, and each tube is provided with an inflating-tube F. In applying this cushion to a rocker the rocker is 9 5 first provided in its under side with a groove concave in c1'oss sectio11. This groove extends the full length of the rocker. Upon each end of the rocker is secured the cap D, which is trough-shaped and is open at one end and the top and closed at the outer end. The cushion B is placed in the said groove in the rocker. The ends having thereon the caps O are inserted in the caps D, in which place they are held by means of the screws E. The cushion is then inflated by means of an airpump applied to the tube F. Proper tension is then applied to the cushion by turning the adj usting-screws E to the right or left, as may be required. If after much use the cushion becomes too loose in its seat, a suitable tension may be imparted to it by properly turning the adjusting-screws E. These screws may serve the double function of adjusting the tension of the cushion and also as the meansfor securing the cushion from displacement from its seat.

A rocking-chair or cradle provided with cushions of our invention upon its rockers may be rocked upon a very rough surface with no perceptible jar to the occupant of the chair or cradle.

As stated before, many modifications may be made from What we have shown and described without departing from the spirit of our invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patcut, is-

1. In a rocker-cushion, the combination with a rocker of the kind described, of an inflatable tube of resilient material having its ends closed disposed lengthwise upon the under side thereof and having one end secured to one end of the rocker, a cap provided with a screw-threaded opening upon the other end of the tube, an adjusting-screw rotatably seing cushion disposed lengthwise upon the under side of the rocker, the caps G upon the ends of the said cushion, and the adjustingscrews E connecting the caps 0 adjacent to the caps D, substantially as described.

3. In a rocker -cushion, the combination with a rocker provided with a longitudinal groove in its under side, of two caps secured one to each end of the rocker, an adjustingscrew rotatably supported in each cap, a resilient cylinder located in the said groove, and means provided by which the ends of the cylinder are united by screw-thread connection with the two adjusting-screws respectively, substantially as described.

4. In a rocker-cushion, the combination with a rocker of the kind described, of an inflatable tube secured to the under side thereof at one end of the rocker, a cap provided with a screw-threaded opening upon the other end of the tube, a support on the adjacent end of the rocker, an adjusting-screw mounted in the said support and engaging the cap, and a valve through which air may be introduced into the tube, substantially as described.

5. In a rocker-cushion, the combination with a rocker of the kind described, of an inflatable tube located upon the under side thereof and secured at one end to one end of the rocker, a pipe extending from the inflatable tube through the rocker for the introduction of air into the inflatable tube, a valve in said pipe, a support at the other end of the rocker, an adjusting-screw mounted in said support, and means for uniting the adjacent end of the inflatable tube with the adjustingscrew, substantially as described.

In testimony whereof we hereunto aflix our signatures in presence of two witnesses.

JOSEPH H. FINK. RAYMOND ANDLAUER.
